Common Information Model (CIM) for Grid Models Exchange

​​​The CIM for grid model exchange enables exchanges for the data necessary for regional or pan-European grid development studies, and for future processes related to network codes.

Grid model exchange is a complex process covering a variety of use cases, which include the exchange of:

  • Equipment information, which contains power system equipment data; Topology information, which contains topology related information for the grid elements;

  • Information on power system state variables, which contains the results from initial load flow simulation of the system; and/or

  • Steady state hypothesis information, which is valid for newer standards and provides information on load and generation values as well as other input parameters necessary to perform load flow simulations.

In addition, grid model exchange can benefit from information related to dynamics, diagram layout and geographical location for elements in the power system. These features were developed in the latest drafts of the ENTSO-E CIM standards to cover the specific business requirements of TSO grid model exchanges. ENTSO-E CIM standards for grid models exchange are based on the following existing or expected IEC CIM standards:

  • IEC 61970-552: CIM XML Model Exchange Format
  • IEC 61970-301: Common Information Model (CIM) Base
  • IEC 61970-302: Common Information Model (CIM) for Dynamics Specification
  • IEC 61970-452: CIM Static Transmission Network Model Profiles
  • IEC 61970-453: Diagram Layout Profile
  • IEC 61970-456: Solved Power System State Profiles
  • IEC 61970-457: Common Information Model (CIM) for Dynamics Profile
  • IEC 61968-4: Application integration at electric utilities – System interfaces for distribution management - Part 4: Interfaces for records and asset management.

Common Grid Model Exchange Specification (CGMES)

The Common Grid Model Exchange Specification (CGMES) is an IEC technical specification (TS) based on the IEC Common Information Model (CIM) family of standards.​ It was developed to meet necessary requirements for TSO data exchanges in the areas of system development and system operation (e.g. TYNDP and network codes) and was initially published in December 2013.

The CGMES will be used as a baseline exchange specification for the implementation of the Common Grid Model (CGM) methodologies (according to the requirements for the implementation of various network codes; expected by 2015). The CGMES will be applied by applications dealing with power system data management, as well as applicat​ions supporting the following analyses:

  • load flow and contingency analyses,
  • short circuit calculations,
  • market information and transparency,
  • capacity calculation for capacity allocation and congestion management, and
  • dynamic security assessment.

The conformity of the applications used for operational and system development exchanges with the CGMES is crucial for the needed interoperability of these applications. ENTSO-E therefore developed and approved the CGMES Conformity Assessment Framework as the guiding principles for assessing applications’ CGMES conformity. Based on those principles, ENTSO-E operates a CGMES Conformity Assessment Process in order to ensure that the CGMES is properly implemented by suppliers of the applications used by TSOs. Details on the conformity testing are available here.

CGMES version 2.4.15 approved on 7 August 2014 is based on the following documentation

For further details and any questions on the CGMES, contact cgmes@entsoe.eu

Documents relating to the previous versions of the CGMES are available here

ENTSO-E CIM Profile 1

ENTSO-E approved the first version of the CIM based data exchange specfication for grid models in 2009, based on IEC CIM14 (UML14v02) and known as ENTSO-E Profile 1.

Profile 1 is currently valid for ENTSO-E data exchanges until an approved version of the CGMES is implemented and comes into force. The ENTSO-E CIM Profile 1 defines how ENTSO-E members, using software from different vendors, will exchange grid modelling information as required by ENTSO-E and TSO business activities.

To facilitate the implementation of this specfication, in the period 2013-2014, the ENTSO-E CIM Profile 1 document was revised to include the agreements reached in the intero​perability test 2013 which were published as separate annex to the specfication.

The following documentation is available for Profile 1:


Interoperability tests (IOP)

ENTSO-E continues improving the CGMES to cover additional requirements defined in the network codes and TSO needs. For this purpose, interoperability tests (IOP) will be organised to verify future versions of the CGMES. IOP 2015 was skipped in order to be able to focus on the actual implementation of the CGMES 2.4 at TSO sites.

In 2016, ENTSO-E conducted, along with European and American vendors and Transmission System Operators (TSOs), a common information model (CIM) interoperability test — ENTSO-E IOP “CIM for System Development and Operations” 2016. The test was held from 11 to 15 July 2016 at ENTSO-E’s premises, in Brussels.

The future ENTSO-E CIM-based data exchange format, ENTSO-E Common Grid Model Exchange Specification (CGMES), which is based on the International Electrotechnical Commission (IEC) CIM standards 61970 (parts 301, 302, 452, 453, 456, 457, 552) and CIM standard 61968 part 4​, was tested in this IOP on a large number of products. The test is a part of the development process of the ENTSO-E Common Grid Model Exchange Specification.

The key goal was to test and validate the latest IEC draft CIM standards on which ENTSO-E bases the new version of the ENTSO-E CGMES. Therefo​re the main objective of the test was to validate the proposal for CIM extensions that will be included in the next CGMES 2.5 version of the IEC and CENELEC standards or specifications and which will be used to support the data exchanges required by the European legislation.​

To validate the proposal for CIM extensions that will be included in the next CGMES 2.5 version of the IEC and CENELEC standards or specifications and which will be used to support the data exchanges required by the European legislation. This is a minor version based on CIM 16 where backwards compatibility is not broken. The extensions are aimed to fulfil modelling gaps in the following main areas:

  • Dynamic modelling
  • Network Model Management (including Frames, Power System Project (meta-data on change set​ and Manifest) Bidding Area and integration with Market Schedules
  • Availability Plan (outage)
  • Operational limits
  • Production (PowerElectronics)
  • Capacity calculations

Issues recorded during the testing and proposed resolutions are included in the IOP report, along with some guidelines on how to implement the CIM standards within the TSO/utility enterprise. Details on the test procedures and discussed topics are included in the report appendices.

IOP participants have approved the report, making it a basis for further discussions in the ENTSO-E Committees as well as in the IEC TC57/WG13. The implementation schedule for the CGMES 2.5 is subject to an ENTSO-E decision later this year.

Previous interoperability test (Fifth - 2014)

ENTSO-E continues improving the CGMES to cover additional requirements defined in the network codes and/or TSO needs. For this purpose, ​interoperability tests (IOP) will be organised to verify future versions of the CGMES. The last IOP test was held in the week of 14 July 2014 which had the following objectives:

  • To validate test configurations (test data) which will be used for the CGMES conformity on version 2.4.14;
  • To resolve reported issues related to CGMES v2.4;
  • To discuss ENTSO-E extensions applicable for the future version of the CGMES. This development is necessary to satisfy the requirements defined in the European network codes.

The IOP reached its objectives.

CGMES Conformity

​​​​​​​​​​The interoperability of the applications used by TSOs for operational and system development exchanges is crucial and ENTSO-E has the objective to ensure the interoperability via compliance of those applications with the Common Grid Model Exchange Specification (CGMES) requirements (now IEC specifications TS 61970-600-1 and 61970-600-2)​. Thus ENTSO-E approved the CGMES Conformity Assessment Framework which establishes services:

  • to facilitate the elaboration of the IEC specifications TS 61970-600-1 and 61970-600-2,
  • the implementation of the European network codes, and
  • the elaboration of the system development studies, specific power system analysis software and IT systems (both hereafter referred to as Applications) that are used to ensure smooth data exchanges between TSOs.

The current design of the CGMES Conformity Assessment Scheme v2.0 allows assessment of the applications only on certain CGMES functionalities that are supported by the assessed Application, i.e. a theoretical approach is used when initially defining the conformity scheme. Hence declarations of conformity and attestations of conformity shall not be used as a confirmation that an application is fully covering requirements on a specific business process.

It is planned to further develop the CGMES Conformity Scheme to cover relevant procedures and test use cases, so as to be able to test and declare the applications used by TSOs as conform to the requirements of the business processes such as DACF and other operational planning exchanges as well as long term planning data exchanges.

Conformity Assessment Scheme v2.0

Conformity assessment scheme v2.0​​ defines the complete set of documentation (related version of the IEC specifications TS 61970-600-1 and 61970-600-2, test configurations, test procedures, etc​.) valid for this version.

Version v2.0 of the Conformity Assessment Scheme is now available and includes the following documentation:

Suppliers of Applications supporting IEC specifications TS 61970-600-1 and 61970-600-2​ are requested to use the available documentation and test configuration, and submit their Declaration of Conformity at earliest convenience. Version v2.0 of the CGMES Conformity Assessment Scheme is a revision update of some of the test configurations.

Suppliers that have already submitted their Declaration of Conformity for previous versions of the scheme do not need to perform tests with this new version if their Application version remains the same. ENTSO-E will setup the Review sessions in accordance with the processes defined in the CGMES conformity assessment scheme.

Disclaimer:

The models (test configurations) are owned by ENTSO-E and are provided by ENTSO-E “as it is”. To the fullest extent permitted by law, ENTSO-E shall not be liable for any damages of any kind arising out of the use of the models (including any of their subsequent modifications).

ENTSO-E neither warrants, nor represents that the use of the models will not infringe the rights of third parties. Any use of the models shall include a reference to ENTSO-E. ENTSO-E web site is the only official source of information related to these models.​
